Police are appealing for witnesses and dashcam footage as they investigate the death of a woman who was struck in a suspected multiple hit and run.
The 29-year-old victim from Wandsworth was hit by a lorry as she used a pedestrian crossing, before she is thought to have been struck by another lorry and two cars.
None of the drivers stopped after the incident in Tulse Hill, south London on Monday morning, the Metropolitan Police said.
The victim was treated at the scene but pronounced dead at 7.21am.
She has not been formally identified but her family has been informed.
A post-mortem examination was due to take place at Greenwich mortuary on Tuesday.
The junction has been described as “a racetrack of sorts” by one resident, in a letter to Streatham MP Chuka Umunna.
Tweeting under the name Ross Runs, the man said: “As both a pedestrian and a driver, the junction at Tulse Hill encourages some of the most aggressive driving I have seen in London.
“If there is an opposite to ‘traffic calming’ then this is it.”
In a joint statement with MP for Dulwich and West Norwood Helen Hayes, Mr Umunna urged anyone with information to come forward.
They added: “Lambeth Council is working closely with Transport for London on urgently needed changes to the Tulse Hill gyratory which will make it safer for pedestrians and cyclists.
“We are pushing for these works to be delivered as soon as possible, and for any lessons which emerge from the investigation into this appalling incident to be acted upon immediately.”
Police have appealed to all four drivers to come forward.
Acting Detective Sergeant Alastair Middleton said: “We want to hear from anyone who travelled from the south circular junctions of Norwood Road going towards the junction of Brixton Hill between the hours of 6.30am and 7.00am on the day of the collision.
“We are particularly interested in any dashcam footage that may have captured some of the incident before or after the collision.
“We are also appealing for anyone who was passing and witnessed the collision and the moments afterwards to contact us immediately.
“Enquiries are continuing to trace all the vehicles involved. A number of actions, including the recovery of local CCTV footage are in hand. I would urge the drivers of all four vehicles to come forward and speak with my team.”
Members of the Tulse Hill community reacted with shock.
Navin Bagan, 37, who works at the nearby Tulse Hill cafe, described the hit-and-run drivers as “heartless”.
“They just left her to die – it is not right,” she said.
“This road is sometimes very busy in the mornings, but that’s not an excuse for a car to hit a lady and run off.”
